How we worked this out
Temperatures and rainy days come from Open-Meteo ERA5 records for 2019-2024 for each city. Where a city's best months were checked by hand against crowds and local seasons, that is the pick shown; otherwise the pick is based on weather alone and is marked. Weather changes from year to year, so treat this as a planning guide, not a forecast.
